Specification of Letters Patent.

Patented Apr. 255, 1916.

Application filed September 15, 1914. Serial No. 861,839.

To all whom it may concern:

Be it known that I,J0HN L. HILL, a citizen of the United States, and a resident of Bowling Green, in the county of Wood and State of Ohio, have invented certain new and useful Improvements in Thresholds, of which the following is a specification, refer ence being had to the accompanying draw ings.

My invention has for its object to improve the construction and operation of that class of sills used in connection with doors, to the end that a stormt-ight union will exist between the door and the threshold.

Another object is to provide a water and wind tight threshold, of a simple and inexpensive nature whichcan be adjusted to any conventionally constructed door, to prevent a draft upon the floor near the door, as well as preventing any water entering the room.

With these and other objects in view, the present invention consists in the combination and arrangement of parts as will be hereinafter more fully described and finally pointed out in the appended claim, it being further understood that changes in the specific structure shown and described may be made within the scope of the claim without departing from the spirit of the invention.

In the accompanying drawings forming a part of this specification and in which like numerals of reference indicate similar parts in the several views: Figure 1 shows a perspective view of a door equipped with a threshold embodying my invention. Fig. 2 is a transverse sectional view through the threshold and Showing a broken portion of the door. Fig. 3 is a top view of the threshold. Fig. 4: is a section on line 4, 4: of Fig. 3.

In my present invention I provide a threshold which will not only prevent the entering of any water into the compartment, but will also prevent any objectional floor drafts near the door, thus contributing to the health and comfort of the compartment in connection with which the threshold is employed.

In the accompanying drawings the letter A, represents a suitable door and B, a door frame in connection with which a threshold embodying my invention is shown.

In constructing the threshold, I employ a door sill 1. This door sill 1, has an upper seat Q, formed therein and has secured to it a housing, comprising the base 3, the outer wall 4, the inner wall 5, a top 6, and the central wall 7. This housing forms a continuation of the sill, as shown in Fig. 2. The inner wall 5, is secured to the inner edge of the sill 1. By means of the walls 5 and 7, a channel at, is formed within the threshold. Itesting upon the top 6, and the seat 2, of the sill 1, is the sectional tread plate 8, 8 preferably made of two strips of brass arranged in parallel spaced relation having inner beveled edges to provide a splayed slot 9, which is located immediately above the channel at, this construction being clearly shown in Fig. 2. Along its inner edge the top 6, is provided with a lengthwise extending indentation or depression 0, clearly shown in Fig. 2, within which are held the ears 12 extending from the shoulders 10, of the rub-plates 11, two such rubplates being used. The upper faces of the cars 12, lie flush with the face of the top 6.

As shown in Fig. 4., each rub-plate 11, has its ends 13, flanged upward and inward, one of these ends being made to do service in slidably holding a spring 15. In Fig. a, one of these rub-plates and springs is shown. Projecting partly through the splayed slot 9, formed between the rub-plate 8, 8, and held near each end upon the springs 15, is the follower 20, in the form of a metal tube arranged to engage within a groove w, formed within the lower end of the door. The walls 4, 5 and 7, are connected by means of the housing ends 19, which extend over the ends of the sill 1, as shown in Fig. 3. Drain openings 22, are formed within the bottom 3, as shown in Fig. I, so that any moisture that might collect within the housing will find a ready escape. It is of course understood that the parts are all made of non-rusting material.

Screws a, are used as shown in Fig. 3, to secure the sectional tread plates 8, 8, to the housing top 6, and the door sill 1. In Fig. 3, I have indicated in dotted lines the cars 12, by means of which the springs may be shoved from end to end to insure proper adjustment of these springs below the tubu lar follower 20.

It is of course understood that these thresholds may be made in various sizes. The threshold is simple and inexpensive in construction, and both durable and efficient in operationv and can be conveniently ad- Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents Washington, 10.0.

rub-plates within the channel of said houseach ending in an ear, said ears held within said depression,a spring carried upon each rub-plate, and a tubular follower held upon said springs and partly projecting through the slot of said tread plate.

In testimony whereof I aflix my signature, in the presence of two witnesses.
